Comment 5 for bug 1229849

Clint: If this feature is actually useful/needed to TripleO, would it be better for Heat to not remove instance_user, but instead just flip the default to not create any user?

Then the instance_user=heat-admin in tripleo-image-elements/elements/heat/os-apply-config/etc/heat/heat.conf would still work, but we'd achieve (AIUI) the objective of the deprecation, which was to stop creating default users on native server resources?
